Hello My name is Eric VanGoeye with VanGoeye home improvement, we charge $400-500 per Sliding door. This will give you a rough idea for cost. If you would like to set up an appointment, just let me know. You can call me at Thanks for checking.. Eric

This is just a starting point

Would be happy to help install the door. There can be several factors that would change the price including: correct sizing, correct model, rot, and other factors. I live close to your area, so would not be a problem to take a look at your project. If interested, please request an appointment. Thanks Dan Allen
